ACCOUNT SYSTEM.

Specification of Letters Patent.

Patented Oct. 20,1908.

Application filed. March 30, 1908. Serial No. 42!,268.

To all whom 'it may concern:

Be it known that I, HENRY VVILKE, a citizen of the United States of America, and a resident of the city of Seattle, in the county 4 of King and State of Washington, have invented certain new and useful Improvements in AccountSystems, of which the following is a specification,

My invention relates to improvements in account systems wherein record cards or the like are employed.

The primary object of my invention is to facilitate identification of any desired card of a group or series.

ln the drawingreference' numeral 1 designates a record card and 2 a guide card. These cards are arranged substantially as illustrated inv Fig. 2, where it is designed to associate a guide'ca'rd with a particular group of record carols. v v

For convenience in'Fig. 2 is illustrated ten record cards in the first group, which are related to. the guide card. bearing the letter A, while but four record cardsgare indicated in the rear group relating to the guide card bearing the letter B. It will be obvious however, that any number ofjgroups of record cards may be employed, and'that each group may comprise a suitable number'of cardsand have associated therewitha guide card.

In carrying out my invention I provide the record card 1 of each group with top marginal projections as 3, which extend one beyond the other" and have their outer end edges beveled, whereby portions 4 of the projections 3 appear in inclined relations above the record cards. On these portions 4 the names of persons with Whom accounts are kept are written in line with the inclined edges. Thus the names may be read more easily when desired-to select from the group a card pertainingto any articular account.

Byslanting. theend e ges of the proj'ec.-

tions 3, as heretofore described, a com aratively long field. for writing is afiorde on each, which field may be further bounded by a line or mark as 7 extending parallel with the beveled edge.

The marginal projections 3 are preferably provided with tabs 5, which are numbered consecutively in respective groups of cards, and the portions 4 likewise numbered, as clearly shown in the drawing. On the projections 3 I may also provide an alphabetical and numerical index, as at 6, the letter designating the group to which the record card belongs and the number the position of the card in its group.

While I have illustrated my invention applied to record cards such as are suitable for keeping accounts in a banking system it may be applied to cards for other analogous uses;

As the full names of persons having accounts are recorded on the portions 4, it is obvious that the card bearing the desired account may be readily selected from the group by the name it bea'rs. This enables a bookkeeper unfamiliar with the numbers of the different accounts to rapidly operate the system. Having thus described my invention, what I claim as new and desire to secure by Let ters Patent of the United States of America,

1. A group of record cards provided with marginal portions projecting one beyond the other and having edges slanting outwardly I from respective cards.

2. A group of record cards provided with marginal extensions projecting one beyond the other along the upper edges of the cards, the projecting portions of said extensions having edges slanting outwardly from respective cards.

3. A group of record cards provided with marginal extensions projecting one beyond the other and terminating in beveled end edges, each of said extensions having a guiding mark extending substantially parallel with its beveled edge,,substantially as and for the purpose speclfied.

Signed at Seattle, Washington, this 21 day of March 1908. V
